Have TeX determine whether or not the page is even or odd and then 
include the graphic file:

\newlength{\negevenjump}
\newcommand{\bigfig}{%
\ifthenelse{\isodd{\thepage}}%
% then set \negevenjump to zero;
{\setlength{\negevenjump}{0mm}}%
% otherwise set \negevenjump to a value which makes the graphic
% aligned with the left margin of even numbered pages.
{\setlength{\negevenjump}{-\marginparsep - \marginparwidth}}%
% Now simply include the graphic.
\hspace{\negevenjump}\includegraphics{yourfigname}
}

I haven't tried this, but it gives you the general idea (I have simply 
modified some code we have to do this from a book we are writing). Note 
it does not use the figure environment, which gives a float, so you 
will have to determine the placement of your figure and create the 
caption.

You might also search for this in comp.text.tex on Google.

Good luck,
